EV/PV integrated charging system

1) Sustainability Problem:

As is well understood, the greater the percentage of EV fuel derived from renewable sources, the greater the sustainability edge is to electrified transportation over fossil-fuel based transportation.

The need for separate electrical equipment to handle PV capture and EV charging is both a cost and a hassle barrier to adoption. Not all PV users drive EV’s, and not all EV drivers have roofs with PV panels but this is a population which will grow exponentially as both technologies improve and become ubiquitous.

The increased efficiency in EV charging by leveraging gathered solar energy at the point of collection is a material gain to the consumer/homeowner.
From the manufacturer:
The SolarEdge HD-Wave inverter with integrated EV charger offers homeowners the ability to charge electric vehicles up to six times faster than a standard Level 1 charger through an innovative solar boost mode that utilizes grid and PV charging simultaneously. This product is the first PV inverter-integrated EV charger.
The SolarEdge HD-Wave inverter-integrated EV charger reduces the hassle of installing a separate standalone EV charger and a PV inverter. Furthermore, it eliminates the need for additional wiring, conduit and a breaker installation. By installing an EV charger that is integrated with an inverter, no additional dedicated circuit breaker is needed, saving space and ruling out a potential upgrade to the main distribution panel.

3) Organizational stakeholders

  1. utilities
  2. public service commission / regulators
  3. EV manufacturers
  4. PV manufacturers
  5. banks providing clean energy financing products

4) Steps in deploying this technology

  1. partner with solar installers to promote PV/EV option over standard grid connection
  2. develop innovating PV/EV rebate programs from state governments
  3. mandate utilities to market/offer inverter charging equipment

One thought on “EV/PV integrated charging system

  1. An interesting idea but I wonder what the role of ‘solar’ energy is here. Is this not just analogous to ramping up to a higher voltage for faster charging, and could be done without solar, like a Tesla’s ‘supercharger’ does? Similarly, is there any actual benefit to putting solar directly into your EV rather than the grid in the larger sense? Yes your individual car is greener, but its not like that energy wasn’t going to be used large scale had you just net metered it back to the grid. I guess my concern with this technology is that it may be cashing in on consumers who care about the image of renewables, without having any actual impact on emissions in the bottom line.
